WINDOW-FRAME PROTECTOR.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed January 3, 1918. SerialNo. 210,179.

To all whom it may concern."

Be it known that I, DWIGHT L. FULTON, a citizen of the United States, residing at Marblehead, in the county of Essex, State of Massachusetts, have invented certain newof a room and this Objection has been mainly due to carelessness in milling the wooden frame work with a result that .the frames prove defective when assembled.

It is therefore proposed, in the present invention, to overcome the above objection by providing a protecting device secured to the window jamb and sill in such manner that leakage of rain through the joints of the frame will be effectively prevented.

It is further proposed to prevent accidental detachment of the parting strips of the window j ambs from their grooves owing to warping of the same.

It is a further object of the invention to provide a device of this character which is' simple in construction, easy to manufacture and which may be readily and quickly applied to its operative position.

The inventive idea involved is capable ofreceiving a variety of mechanical expressions one of which, for the purpose of illustrating the invention, is shown in the accompanying drawing, wherein Figure 1 is a fragmentary front elevation of a window frame and showing one of the devices applied thereto.

Fig. 2 is a transverse section through the sill of the frame showing the device in edge elevation.

Fig. 3 is a horizontal section through the frame showing the device in plan view.

Fig. 4 is a section on the line 44 of Fig. 2.

Fig. 5 is a detail perspective view of one of the protecting devices.

In the drawing, there is illustrated a portion of one side of a window frame of ordinary construction which includes the sill 10 which is inclined as usual and adapted to have a portion thereof mounted in a diagonal groove 11 formed in the window jamb or pulley stile 12. This jamb is connected to the outer casing 13 by a tongue and groove joint 14 and is provided adjacent its outer vertical edge with the groove 15 for receiving the parting strip 16 which forms a guide for the upper and lower sashes of the window. In window frames of this well known construction, certain defects are noted owing to carelessness in milling the different parts and these defects reside principally in the failure to make tight joints and having the abutting surfaces of the sill, jamb and outer casing in flush engagement with each other thus permitting water to leak through these joints and spaces left between said parts with resultant damage to the interior of a room. Another defect, which has oftentimes become apparent after the window frame has been assembled and in position a length of time, is occasioned by the warping of the parting strip 16 in its groove 15 which eventually results in either a partial or total detachment of the strip from the jamb which fact necessitates repairs being made.

The pnesent invention, which is designed to overcome the above objections, is shown in the accompanying drawing in what is now believed to be its preferred form and.comprises a protecting device for each side of the window frame which is formed from a single sheet of material, such as copper or zinc composition. This sheet of material is preferably stamped to form the fiat base 17 consisting of the angular portions 18 and 19 andhaving a plurality of small openings 20 therein for receiving fasteners which aid in securing the base to the sill 10. The portions 18 and 19 of the base are adapted to be interposed between the sill and the lower edges of the jamb 12 and outer casing 13, respectively, and the inner edge of the portion 18 is provided with an angularly disposed flange 21 which is provided with transverse corrugations 22 throughout its length and which has its free longitudinal edge sharpened as indicated at 23 so that said flange may be readily'driven into the material of the jamb 12 along the upper edge of the groove 11 therein. This flange not only aids in securing the device in proper position but also prevents the leakage of water into the space, which is usually left between the upper surface of the sill and the upper edge of the groove 11 owing to the imperfections in the construction as, previously noted. The portion 19 of the base is also provided upon its inner edge with an angular flange 24 which is of greater width than the flange 21 and has the end thereof adjacent the inner corner of the base interposed between the forward edge of the window jamb and the adjacent surface of the outer casing. The remaining portion of the flange 24 extends'along said surface of the casing and tightly engages the same so that water leaking between the sill and the lower edge of the outer casing will'be prevented from passing beyond the parts by said flange. .It will thusbe apparent from the foregoing description that the device provides an effective protecting joint which will by reducing the same as indicated at 26. It 'will be apparent from this construction that 85 itself from the groove by if the lower end of the strip 16 should warp the same will be prevented from detaching the stop 25. What is claimed is Y 1. In a window frame, the combination with a sill therefor, the window jamb and outer casing; of a protecting device having a base including angularly dlsposed portions lying in the same plane and interposed between said jamb and casing, and said sill, and

a and engaging a vertical casing.

' 3. In a window frame, the combination means for securing said device in position.

2. In a window frame, the combination with a sill therefor, the window jamb, and outer casing; of a protectin device having a base including angularly disposed portions arranged in the same plane, interposed be tween said jamb and casing, and said sill, and a flange disposed at an angle to said base side of said outer with a sill therefor, the window jamb, and outer casing; of aprotecting device having a base interposed between said jamb and casing, and said sill, a flange on one inner edge of the base disposed at an angle thereto 7 and engaging formed upon one of portions,

- from the thereof.

a vertical side of said outer casing, and a second flange on the. other inner edge of the base extending therefrom and embedded in said jamb.

' 4. In a window frame, the combination with a sill therefor, the window jamb, and outer casing; of a protecting device having a base interposed between said jamb and casing and said sill, a flange disposed at an angle to said base and engaging a vertical side of said outer casing, and a second corrugated flange having a sharpened edge embedded in said jamb.

5. In a window frame, with a sill. therefor, the window jamb and outer casing; of a protecting device having a base. including angularly disposed portions interposed between said ing, a corrugated flange formed upon an edge of one of the portions of said base and embedded in said jamb, and a second flange formed upon an edge of the other portion of said base and engaging a surface of said outer casing.

6. A lprotecting device for window frames formed from a single sheet of material including a base having angularly disposed portions, and a corrugated securing flange formed upon one of the longitudinal edges of one portion and having its free longitudinal edge sharpened.

7 A protecting device for window frames formed from a single sheet of material including a base'having angularly disposed portions, a corrugated securing flange the longitudinal edges of one portion and having its free longitudi' nal edge sharpened, and a second flange disposed along the adjacent longitudinal edge of the other portion of said base.

- 8. A protecting device for window frames formed from a single sheet of material including a base having angularly disposed a corrugated securing flange formed-upon one of the longitudinal edges of one portion and having its free longitudinal edge sharpened, a second flange disposed along the ad acent longitudinal edge of the other portion of said base, and a lug struck first mentioned portion of the base and adapted to engage the parting strip of a. window frame to In testimony whereof, I aflix my signature in the presence of two witnesses.
